Kevin Xu turned a $35,000 retirement account into $8 million and posted every trade on r/wallstreetbets as Sir Jack A Lot, dollar amounts and all. Then he built a company because people kept faking that kind of screenshot. Here is who he is, what the public record shows, and why his story is an argument for checking records instead of trusting legends.

CK Capital's X banner is a single word: conviction. The account posts small-cap AI and photonics theses at a dozen a day and keeps turning up in our own receipts tables, so we graded the conviction: 2,229 tracked stock posts since March, a fourteen-to-one bullish lean, and 103 graded calls at 54.4% right. Here is who they are and what the record shows.

The companies that drew the most discussion across the accounts we track in August 2026, with the sentiment split, the share from voices with a track record, and how each one's month ended.

TheValueist is the most prolific account Quantral tracks: 4,949 stock posts since May, its own research site, and a bio that says results never lie. We graded 71 of those calls: 54.9% right, sixth on our six-month accuracy board. Here is who they are and what the record shows.

AMD beat and raised guidance, launched the MI400, and partnered with Anthropic, yet the stock round-tripped a 7% pop in a day. Across the Reddit and X accounts we track, even the high-track-record voices split on AMD, so Quantral's sentiment score stayed at a neutral 49.

Yesterday we published the room's read on Nvidia hours before the print: crowd 3-to-1 bullish, the tracked accounts at 6-to-1. Nvidia beat on everything and guided nearly $4 billion above consensus. The grade, the caveat from May, and the one chart that shows who showed up after the fact.

Nvidia prints after the close. Across the accounts Quantral tracks: 386 mentions in three weeks, a crowd running 3-to-1 bullish, and the accounts with real track records at 6-to-1. In July, Tesla and Alphabet went into their prints on 10 to 13 percent trusted volume. Nvidia goes in at 30 percent.

Moderna, Nebius, and Micron drew the most talk across the accounts Quantral tracks over the week of Aug 17 to 21. The loudest name on the board carries the lowest score on it, the most credible room had its worst week since July, and the best call of the week came from a room too small to make the table.

Jim Cramer named four memory stocks on Mad Money. Across the accounts Quantral tracks, the trusted voices backed Micron and SanDisk weeks earlier, still doubt Western Digital, and have no read on Seagate.

jukan05 is the new handle of Jukanlosreve, the semiconductor account behind the DeepSeek PTX story and a stream of Korean chip-industry scoops. Quantral has graded 70 of their stock calls: 58.6% right, third on our six-month accuracy board. Here is who they are and what the graded record says.

aleabitoreddit, the X account known as Serenity, went from a wallstreetbets ban to a million followers on supply-chain calls like AXTI and AAOI. Quantral has graded 274 of those calls: 59.5% right, second on our six-month board. The record is real. It is also smaller than the legend.

On August 7 we wrote that SpaceX's lockup would be the first real test of Quantral's flipped score: 19 for a month, then 77 after the first earnings report, while the crowd stayed two to one bearish. The test came and went. SPCX cleared the unlock, closed back above its $135 first-day price, and finished the week at $140.00, up 21.8% since the post ran.

Applied Optoelectronics fell 62% from its June peak. Quantral published its score five times along the way, never below 71, while the graded accounts ran 7-to-1 bullish. Then Q2 landed and the stock closed 80% above the low.

Nebius lost almost half its value between June 18 and July 29, and across the accounts Quantral tracks, bearish calls did not outnumber bullish ones on a single day of it. Of the 15 big drawdowns in our coverage that summer, it held the widest credible split. Then Q2 revenue came in up 454%.

Micron ran 3.5-to-1 bullish and Western Digital 2-to-1 bearish across the accounts we track. Then the two stocks went different ways. The full MU, SNDK and WDC split.

Retail has net-bought SpaceX every single day since the IPO, and today roughly 912 million locked-up shares come free. Quantral read the name cold for a month at a score of 19. After the first earnings report it flipped to 77, while the raw crowd stayed two to one bearish. The gap between those two readings is the whole story.

Coherent lost nearly half its value between June and late July. The Quantral score never turned with it, holding in the 80s and low 90s on a handful of accounts with real track records. Then the price came back 46% to meet it.

Early August's conversation looked like a rotation into software and chips. It was an earnings week in disguise: Palantir, AMD, and Applied Optoelectronics pulled the crowd in on August 4. The score rated them 80, 41, and 87, and the spread is the whole point.

Nebius drew 843 mentions across the finance X and Reddit accounts we track, ahead of Meta and NVIDIA. The top ten, with sentiment splits and trusted-voice share.

The standing Friday scorecard, in the loudest earnings week of the season. The AI-infrastructure names the credible rooms have been long all month fell as much as 21% by Wednesday, then Microsoft's blowout print snapped the whole trade back on Thursday. The honest part: one earnings report whipsawed the entire tape, and the biggest mover of the week, Microsoft itself, walked in with a quiet, undecided room the score never called.

The script the whole room was reciting, beat, raise capex, dump anyway, met the numbers last night and split down the middle. Microsoft beat everything and its room is 64% bullish since the print, score up from 68 to 83. Meta missed on earnings, raised its capex floor, and its room turned 56% bearish, score down from 61 to 38. Tonight the last two report: Apple, loud and at record highs with a score that has cooled from 81 to 45, and Amazon, which almost nobody in the accounts we track is talking about at all.

The Fed decides at 2pm, Microsoft and Meta report after the close, and in the accounts we track both names walk in quiet and split: 34 and 49 mentions on the week, scores of 68 and 61, and one shared script, that both will beat and still fall on higher AI spending. The room's real conviction sits with the companies on the receiving end of that spending. And the Fed? About one mention in thirty.

MaxLinear delivered the quarter its bulls wanted, revenue up 55% with a raised guide, and the stock still fell 29% in two sessions. Before the print, every account talking about it in our set was a trusted one. After it, the room stayed seven-to-one bullish while the tape went the other way. That is the widest gap between a credible crowd and a price on our board right now, and this is how it gets graded.

Microsoft and Meta report Wednesday, Apple and Amazon Thursday, with the Fed deciding in between. In the accounts we track, all four are quiet going in: 11 to 53 mentions each over the week, against 185 on Nebius, and only a handful come from an account with a track record. The pre-print lean is thin and split, so it reads as expectation, not conviction. The credible rooms are parked where they were, on the AI-infrastructure names and on Alphabet after its print.

Two days ago both names carried a warm but thin-credibility bullish lean into their prints. Both then fell, Tesla 14.5% and Alphabet 7.1%, so the lean did not pay. What split was the response: Tesla's room flipped bearish, while Alphabet drew nearly triple the trusted share and stayed bullish, leaning into the drop. And the Fed decides Wednesday.

Intel prints after the close tonight. In the accounts we track it is the only semiconductor name where bears edge out bulls, 39% to 35%, while the rest of the chip trade leans confidently long. But that split comes from the most credible room in the group, 43% of its mentions from accounts with a track record, so it reads as genuine disagreement among people who have been right before, not low-conviction noise.

Both megacaps print after the close on Wednesday. Over the last seven days the accounts we track got louder and turned net bullish on both, and their scores rose. But only about one in ten of those mentions comes from a trusted account, so it reads as expectation building into a catalyst, not the credible conviction the score usually rewards.

Last week one stock we track jumped 22% in a day and another fell hard on earnings. Each drew a flood of mentions, but the two crowds looked nothing alike, and that difference is the whole point of weighing who is talking.

Alphabet, Tesla and Intel all report this week, but the accounts we track are barely talking about them. The loudest, most trusted rooms in our data are names that do not report at all: an AI-infrastructure build and a small cluster of optics stocks.

The standing Friday scorecard. The quietest one-sided room on the board (Aehr Test Systems) got paid 24% in an earnings week, the cold reads on SpaceX and Oracle kept paying, and the honest part: the loudest bullish rooms of the week, Nebius and SanDisk, got hit the hardest.

A jury convicted Andrew Left in June. We graded every Citron Research call from January 2025 to the final post: 12 of 15 right at 90 days. The case was never about the calls.

Half of everything is technically 'Technology', which is how sector maps hide rotation. So we re-cut two weeks of market chatter into the corners the crowd actually talks in: platforms doubled their share twice over, memory is still the loudest single room, photonics is the most trusted one, and the restaurant saga emptied out.

SpaceX priced the biggest IPO in history, ran 57% in four sessions, and has been sliding ever since. Quantral's score has read it cold the whole way, because the accounts with real track records were the ones saying no. This is what a credibility-weighted signal looks like when fame and conviction point in opposite directions.

Penguin Solutions' beat-and-raise week, Meta's double-digit run, and a SpaceX slide the score never bought. Where Quantral's score and the crowd parted ways over Jul 6 to 10, and how those calls resolved.

Five of America's biggest banks open Q2 earnings season on Tuesday, and the accounts Quantral tracks gave them one mention all week. Here is what the crowd is actually loud about going into the reports, from a split, bearish-leaning Netflix room to a credible TSMC build.

For five weeks, a small, credible crowd made 80 directional calls on Penguin Solutions and exactly one of them was bearish. The stock chopped sideways the whole time. Then earnings landed, and it closed up 25% in a session. Here is what that kind of quiet unanimity looks like before it resolves.

We graded every account we track that has a real track record. The distribution is not a bell curve, it splits in two, and the credible minority carries almost all the correct calls. Here is what it looks like, and two names that show why loudness is a bad proxy for it.

Reddit drew one of the loudest, most divided conversations on Quantral last week, yet it held the single highest score on the board. Here is why: the bulls and bears were both credible, the doubt was concentrated in the least credible voices, and the stock ran about 27% off its low.

Wendy's, Micron, and Nebius drew the most talk across the accounts Quantral tracks over the week of Jun 29 to Jul 3. But loudest is not the same as strongest. Here is where the volume and the credible read agreed, and where they split.

When SpaceX priced the biggest IPO in history, WSB bet that shut-out retail would pile into the lookalike ticker: Virgin Galactic. For 48 hours SPCE was one of the loudest names we track, and essentially none of it was about Virgin Galactic. The score held at 39. Two weeks later the stock was at half the pop.

When FuelCell sold off hard in June, the crowd talking about it was not a meme mob. Almost every voice was a trusted one, and they called the bottom. The score read it, the stock ran 92% off the low, and this is why who is talking beats how many.

We mapped a month of market chatter by sector. Technology drowns out everything else, but the loudest sector is not the most bullish one, and the most bullish sectors are the ones nobody is talking about.

The quarter closed on June 30, so we graded every call the accounts we track made in Q2 and ranked them by verified accuracy. Twelve voices cleared the bar. Here is who, and what a quarter of being right actually looks like.

Instead of one autopsy, a month-end look at where Quantral's score and the crowd parted ways in June, and how those calls resolved. In a down month for tech, the cleanest cases on both sides went the score's way.

Over the week ending June 29, Quantral tracked 4,800 mentions across 240 names. Rank them by volume and rank them by signal score, and you get almost two different lists. A look at the gap between how loud a stock is and how strong its signal is.

Wendy's drew more finance chatter this week than Micron or NVIDIA. But only 17% of it came from voices with a track record, and Quantral's signal held at a lukewarm 63. A look at why volume isn't conviction.

A look back at one real Quantral signal. Micron went loud on May 26, before a 61% run and a sharp pullback. Here is what the signal showed, in time, and what it did not.

Over the past month we graded thousands of stock calls across finance X and Reddit. Five lessons held up across every dataset.

We ran every gradeable r/wallstreetbets call from six weeks through the same scoring we use on every voice Quantral tracks. The verdict: worse than a coin flip, and much worse when the crowd shorts.

We graded six months of calls from the finance voices Quantral tracks. Volume tells you who's loud; this tells you who's actually been right. Here are the ten most accurate.
